At this time, the rotation of the transmission gear 605 will drive the tooth plate 1 606 on both sides to move to the left, thereby pushing the push plate 607 to move inside the lower hopper 5, so that the material inside the lower hopper 5 is quickly transmitted to the inside of the discharge roller 7, and then the discharge roller 7 further stirs the material to make it more uniform. At the same time, it can effectively improve the cleanliness of the inner wall of the lower hopper 5, reduce material waste and prevent mixing with different materials.

[0028] Here’s how it works:

[0029] First, after the personnel draws the material into the lower hopper 5 through the pipeline, the motor 601 can be controlled to rotate slowly. At this time, the bevel gear 1 602 will drive the bevel gear 2 603 to rotate. At the same time, the bevel gear 2 603 and the transmission rod 604 will drive the transmission gear 605 to rotate.
